Visualization

Contrast visualization can be computed from this stage's binary data combined with block map and original fingerprint image.
Visualization itself is not part of transparency data.

Contrast map. Circle's surface area is proportional to contrast within that block.

Binary data

Binary data is a 2D array with dimensions that can be found in the associated json data, height first,
and that are also equal to the number of primary blocks in the block map.

Binary data consists of rows of primary blocks ordered from top to bottom.
Every row is a sequence of blocks from left to right.
Every block is a 64-bit IEEE754-encoded big-endian floating-point number
in range from 0 (no contrast) to 1 (maximum contrast).
